STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning ( Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

Project Title: Collaborative Research: Microbial carbon cycling and its interactions with sulfur and nitrogen transformations in Guaymas Basin hydrothermal sediments Project Status: Submitted
Principal Investigator: Andreas P. Teske, UNC_CH Project Institution: UNC_CH
Project ID: 103998 Version #: 1
Date Submitted: 8/13/2013 12:25:00 PM Created By: Andreas P. Teske

Funding Agencies: NSF/OCE/BIO - 1357238 - Funded
Summary of Field Work: We are planning to perform an integrated microbiological and geochemical study of hydrothermal sediments in Guaymas Basin. We are planning Alvin dives to the hydrothermal vent fields of Guaymas Basin (Southern trough) at 2000 m depth in the central Gulf of California. Alvin will recover sediment cores, microbial mats, and marine invertebrates from the hydrothermally heated sediments in the southern portion of Guaymas Basin.
Summary of Facility Requirements: We will need RV Atlantis and Alvin for video and photo surveys, temperature probe measurements of hydrothermal sediments, intrument deployment and sediment pushcore sampling. We may also need an elevator for pre-dive deployment and post-dive recovery of bulkier equipment or heavy core loads. We will bring long (24") coreliners for Alvin pushcoring; these have proven very effective for pushcoring hydrothermal and seep sediments on cruises AT15-56 and AT18-02, and they really raised the quality of work from this cruise.
Summary of other requirements and comments:
Summary of other requirements and comments: We generally prefer Alvin over ROVs. On the three prior cruises with Atlantis/Alvin in Guaymas Basin (in 1998, 2008 and 2009; 2000 m depth), and in the Gulf of Mexico (2010; 2300 - 600 m depth), sediment sampling and sample return with Alvin was speedy and effective. We know Guaymas Basin and our sampling sites quite well, and do not need to drive around much exploring and looking for good samples; the dive target positions are reliable and mapped out after two Guaymas cruises. Nighttime work (CCD water column sampling and profiling, elevator deployments, MUC coring) can be organized effectively around the Alvin dives.

Optimum Start Date: 2/1/2016 Dates to Avoid: Start and end dates are quite flexible; Ca. 12 months after the start of the funding period (Feb 1, 2014) would work best, but we are flexible. We can also delay spending funds if a ship time window opens up later in 2015.

Guaymas Basin
Description of Op Area: Guaymas Basin is the deepest part of the Guaymas spreading center in the central Gulf of California, ca. 2000 m deep. The area is hydrothermally active. The seafloor is covered with hydrothermally heated sediments; hydrothermal chimneys, sulfide mounds, microbial mats and vent fauna are abundant. The area is quite compact: On our previous cruises in 2008 and 2009, most dives were in an area of 500 x 500 m. A few hydrothermal features are farther off, but everything is within a radius of a few miles.

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
The cruise can start and end in Guaymas (Sonora) or in San Diego (CA); both ports would work at the start and end of the cruise. Guaymas is much closer to our field site in Guaymas Basin (5 hours transit) and easy for our Mexican collaborators. On the other hand, San Diego as the start and end port would facilitate shipping of samples and supplies by orders of magnitude (not easy and quite expensive in Guaymas).

Science Party
Chief Scientist: Andreas P. Teske, UNC_CH

provided by ship operator:
(include in science party total)
Explanation of Science Party Requirements and Technician Requirements The projection for the science party is 18 to 20: A contingent of 6 to 8 from the University of North Carolina (Chapel Hill), 4 from the University of Georgia (Athens), 2 collaborators from the University of Southern Denmark, and 2 collaborators from the Max-Planck-Institute for marine Microbiology. Two Mexican observers have to be included, and 2 Science support technicians should be included (same as on previous cruises (AT14-40, AT15-56). The total of 18-20 still allows to take representatives of other cruise parties on board, to recover long-term experiments or samples (as done successfully on cruise AT15-56).

A radioisotope van is needed for stable isotope work (13C, 15N) and radiotracer work (low-level beta emitters 14C, potentially 36S) for incubation and microbial rate measurement experiments using time-sensitive, fresh sediment samples.
